            'pager'   => $pager->links(),
        ];
        return $this->response->setJSON($jsonArray);

    You are initializing serialNumber when you receive a ajax response. Do it on page load.

     function show(){
    let ajax = $.ajax({
         url     : '/Controller/method',
         method  : 'post',
         dataType: 'json',
         cache   : false
  });
  
  ajax.done(function(data){
      let serialNumber = 1; // move this to page load
      $.each(data.result, function(k, v){
            html += `<tr>
                         <td>${serialNumber}</td>
                         <td>${v.myColums}</td>
                     </tr>`;
            serialNumber++;
      });
  });

  $('.result').html(html);
}

    Declare a variable outside of the function

    let serialNumber = 1;

function show(){
    let ajax = $.ajax({
        url     : '/Controller/getAll',
        method  : 'post',
        dataType: 'json',
        cache   : false
    });
    
    ajax.done(function(data){
        $.each(data.result, function(k, v){
            html += `<tr>
                         <td>${serialNumber}</td>
                         <td>${v.myColums}</td>
                     </tr>`;
            serialNumber++;
          });
    });
}

    Another option is to return the page number from PHP and calculate the start point of the serial

    You can try this:

    $page = ($this->uri->segment(3)) ? $this->uri->segment(3) : 1;
$data["slno_start"] = (($page-1) * $config["per_page"]) + 1;
